[:SOURce]:POWer:ALC[:STATe] ON | OFFFehler! Textmarke nicht definiert.
The command switches level control on or off.
ON Level control is permanently switched on.
OFF Level control is switched on for a short period of time if the level changes.
Example: :SOUR:POW :ALC:STAT ON *RST value is ON
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude] -144 to +16 dBm
The command sets the RF output level in operating mode CW. UP and DOWN can be indicated
in addition to numeric values. Then the level is increased or reduced by the value indicated under
:SOURce:POWer:STEP.
In this command, the OFFSet value is considered as with input value AMPLITUDE in the
LEVEL-LEVEL menu. Thus the specified range indicated is only valid for :POWer:OFFSet = 0.
The specified range with other OFFSet values can be calculated according to the following
formula (cf. Chapter 2, Section "Level Offset" as well):
-144dBm+ OFFSet to +16dBm +OFFSet
The keywords of this command are optional to a large extent, thus the long as well as the short
form of the command is shown in the example. *RST value is -30 dBm
Example: :SOUR:POW:LEV:IMM:AMPL 15 or
:POW 15
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude]:OFFSet -100 to +100 dB
The command enters the constant level offset of a series-connected attenuator/ amplifier (cf.
Chapter 2, Section "Level Offset"). If a level offset is entered, the level entered using
:POWer:AMPLitude does no longer conform to the RF output level. The following connection is
true:
:POWer = RF output level + POWer:OFFSet.
Entering a level offset does not change the RF output level but only the query value of
:POWer:AMPLitude.
Only dB is permissible as a unit here, linear units (V, W etc.) are not permitted.
Caution: The level offset is also valid in the case of level sweeps!
Example: :SOUR:POW:LEV:IMM:AMPL:OFFS 0 oder *RST value is 0
:POW:OFFS 0
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude]:RCL INCLude | EXCLude
The command determines the effect of the recall function on the RF level.*RST value has no
effect to this setting.
INCLude The saved RF level is loaded when instrument settings are loaded with the [RECALL]
key or with a memory sequence.
EXCLude The RF level is not loaded when instrument settings are loaded, the current settings
are maintained.
Example: :SOUR:POW:RCL INCL
